1 Claim. (Cl. 43-427) This invention relates to a smoke dispensindevice, adapted for use to discharge smoke for exterminating gophers orrats, hich inhabit ground burrows or pockets.

The principal object of this invention is to efficiently discharge astrong blast of smoke into burrows or pockets formed in the ground, todrive rodents or other ground inhabiting animals out of their lairs orto overcome and asphyxiate them, and to dispel bees and similar insects.

Also, it is an object of this invention to provide means for discharginga constant and strong blast of smoke for fumigating trees, bushes andother shrubbery and for utilization and employment as a frost repellingmedium, to protect the fruits of the trees and bushes.

Another object of this invention is to employ means for compressing airand discharging the air within the casing to aid the combustion of fuelplaced withinthe casing and to discharge smoke from without the casing.

A meritorious feature of this invention resides in the provision of abellows bracketed to a combustion chamber and adapted to discharge airthrough the combustion chamber to incite and aid combustion of the fueland to conduct air transversely through the casing, providing a Venturiaction to suck the resultant smoke from the fuel out of the combustionchamber and discharge the smoke out of the casing.-

Another meritorious feature of this invention resides in the provisionof a discharge pipe dctachably secured to a connecting pipecommunicating with the bellows and the casing and transversely extendingthrough the casing to a point without the casing for discharge of thesmoke from the casing to the outer atmosphere.

Another feature of this invention is the provision of a primary sourceof air for combustion, which includes an angular pipe extendinglaterally from the bellows and terminating at a point adjacent thecombustion chamber.

With these ancillary objects and other meritorious features in view,this invention comprises certain structural features and arrangement ofparts as will be more clearly apparent, as the following descriptionproceeds and in view of the accompanying drawings, wherein:

Figure 1 is a side elevational view of a smoking device, constructedaccording to the principles of this invention;

Figure 2 is a top plan view of the device shown in Figure 1, with thecover removed and,

Figure 3 is an enlarged structural view of the means utilized todischarge the smoke from the casing and comprises a tubular dischargepipe.

Referring now more particularly to the draw ings, wherein an embodimentof this invention is shown, for illustrative purposes, and whereinsimilar characters of reference refer to similar parts throughout, thereis shown casing Ill, having its top end open and adapted to a detachablycovered by a cover member 12. Centrally disposed and formed in thebottom end, M, of the casing is an aperture 16, around which is secured,within the casing, a domeshaped wire screen. This screen l8, forms afuel bed for the fuel and defines a combustion chamher within thecasing.

, secure the connection of r having laterally extending ends 3|] andSecured to the side of the casing, adjacent the open end thereof, is adischarge spout or tube 20, of any suitable size and preferably conicalin shape, having its larger end secured to the casing by means of anapertured annular flange 22, formed around the periphery of the enlargedend of the spout. Conventional means are provided to secure the spout tothe casing and include telescopic screws or bolts 24, which are insertedthrough the apertured flange 22 of the spout and through the side of thecasing.

Secured to the casing, on the opposite side from the spout 2B is abellows are provided for attaching or securing the bellows to the sideof the casing and include a pair of oppositely disposed brackets 28,30,utilized to ing, and comprise an elongated plate, of a suitable width tospace the bellows from the casing, 32. Ends 30 are bent at right anglesto the longitudinal plane of the bracket plates 281 and are secured tothe cooperating side 34 of the bellows 26 by means of screws 40, whichare inserted through apertures in the angular ends 30 and penetrate intoand are threaded into the cooperating side 34 of the bellows. Angularterminating sections to conform to the cylindrical contour of the easingand to be seated flush thereon. Telescopic screws, or othersuitablemeans, 42, are employed to secure the arcuate extensions 32 tothe casing l0 and are inserted through apertures formed in the arcuateends 32 and the casing.

The bellows 26 comprises a pair of which are retained in operativerelation, by means of a flexible covering, of suitable material. Thematerial 34 and 36 forming an air-tight chamber therea cylindrical 26.Suitable means the bellows to the cas- 32 are arcuate in cross-sectionoppositely disposed cooperating plate members 34 and 3B,

46 covering the cooperating plates between, when the plates areextended, is fixed or secured to the sides of the plates 34 and 36 bysuitable means, such as rivets 48.

Disposed within ing sections 58 of the bracket 54 and inserted throughthe bottom of the casing. V

oppositely disposed from the conical spout and in horizontal alignmenttherewith is a suitable aperture formed inthe opposing sidewall of i andsecures wall of the casing.

The fuel placed on the fuel bed is then ignited and the cover I2-isreplaced on the top of the casing. The bellows 26 is compressed and airis sucked in the bellowson the release stroke, when the" 34 and 36 areurged apart by the spring 72. When the'cooperating plates are end 52,
